I have a huawei u8160 running Cyanogenmod 7.2 16/8/2012.
I've installed the external usb host package then the usb host worked after some trouble using this code :
su
insmod /system/lib/modules/ehci-hcd.ko
that activated the usb host mode but I found that my sd-ext was not mounted correctly , so I wanted to know : How can I activate my usb host while avoiding unmounting of sd ext?
